"Asynchronous development" means that one developed unevenly, particularly in their neurological traits. NTs develop more evenly (in that regard). There are gifteds who have developed evenly, too, but they are the exception rather than the rule.
The last time I took the WAIS(-IV),* my sub-scores had a 43 point spread. I am told that they are typically much less spread among NTs.
*It is the only one where I had access to the raw numbers.

One of my issues isn't far from David Wechsler's, in that I don't understand how you can quantify something you don't understand. I've been considering my Reiki, as it disproves the unempathic thesis. Let's go into it.
Firstly, at master level, it's telepathic. I share most traits with Usui's original circle, a diplomat in Peace-making, using Zen Christian meditation, and highly meridian-aware. I "read the room" banally.
Secondly, it's meditative, in other words non-cognitive. It's greatly boosted by my medium gift, tapping the numinous.
Thirdly, it's meridian-powered. I'd been aware of those energy flows from my teenage years, rejected chakras as too crude, and finally found the acupuncture maps as a fair approximation to my experience.
Reiki never crossed my mind until an aura-sensitive told me categorically I have a master's aura. So, hearing of an Open Day from a forum dealing with a polyharmonic instrument, I hied my way to a Healer Sanctuary on the other side of this huge city, and found my way to a meditation. I was a complete stranger to all present, so I read the room and discovered a deficiency in a particular area. I cleansed my channels, and offered power to the area, silently. It was taken. I settled back and waited. Session time done, the leader asked if there were any questions. A hand shot up from the general area, "I've never come out of a meditation tingling before. Is this usual?" I owned up: I hadn't been obtrusive, but facilitating, and someone in that group of four had just grabbed for its need. Test confirmed, and the new practitioner, whose hands-on transfer hadn't worked, was happily taken under the sanctuary's wing to settle her powers.
What had happened is that my service in diplomacy had developed my long-distance broad-range empathy, to understand how a nation I'd never visited felt, to offer viable and realistic help. I later tested it in a tighter focus one-on-one with my mentor, looking into his mind to tell him a deep secret he kept very private. He had plenty of shields, which I respected, but that was visible. It's like Donald Trump's code-breaker in November, I've done that too as a proof of concept, my only crib being a partial knowledge of its contents: system and password took 5 minutes, and assembling the tools to confirm, fifteen. My metamorphic experience involved channelling a power which blind-read a 20-word text I didn't know existed. Strange? You bet. Functional? Very.
